naled in the ends onopposite sides'fof the said piston7.'

The cylinder 1 has an interchangeable live l vand exhaust port 12 on either side ofthe piston 7 nearthe top of said cylinder, and said ports 12 are connected by means of passages 16. Midway between the ports 12 a three- Way rocking valve 14 is -inserted in an opening transversely in the cylinder 1 and intersectin g the passages 18. The valve 14: has an angular port 15 therein, which is arranged in jone position to connect one of the passages 13 with a passage 16 located immediately above said valve and in another position to connect the other passagel and passage 16. The passage 16 is connected to and communicates with-an oscillatin g cut-off located transversely in the top of the cylinder l and composed of the valve 17, which, as shown in cross-section,

Fig. 2, has its top and center cut away, with `a. slot in the bottomside wherewith the supply of motive mixture may be cut off as the valve 17 is oscillated, and a stein 18, rigidly attached concentrically in said valve 17 and extendingV rearwardly through a thimble 19,

provided with a collar or flange 2Ol and attached to the rear side of the cylinder by Aslotted arm 21, having an eye therein, is inserted over and rigidly attached to the stern 18 nearits outer end.

An eccentric 22 is rigidlyattached at a suitable point on the main shaft 6 bymeans of a set-screw 23.. Aneccentric-strap24: receives said eccentric 22 and has an eccentric-rod 25 rigidly attached thereto, `whichnod .25 eX- tends upwardly and is pivotally secured to a block 26, which is adj ustably inserted in the Ioo v,

slotted arm 21 andhas suitable means for se*` Y' `curing thesame in desired position.

The main shaft 6 is journaled in bearings 27, which are mounted on brackets 2S, which are suitably secured on a foundation.

A suitable balance-Wheel 29 is rigidly at- 5 iached to the shaft (i. An ordinarypulley 30 is rigidly attached to the shaft 6 at a suitable point tllereon, from which power may be transmitted as desired;

Immediately beneath the thimble 19 an ex-v ro plosion-chamber 31 is rigidly attached to the side ot' the cylinder 1 by means of suitable bolts. \Vithin the outer end of said chamber 3l a thimble 32 is inserted, preferably by means of a male and female screw-thread. A hollow core 33, having a flange or collar 34 formed on the rear end thereof, is inserted in the thimble and maintained therein by a nut 35, which is screwed on the end of said core and impinges upon the en'd of the thimzo ble 32. Between the parts of the core 33, its

ange 34, and nut 35 and the thimble 32 suitable insulation 36 is arranged. A shaft 37, having a collar 38 suitably located thereon and adapted to engage with the inner end of z5 the core 33, is inserted in said core 33, with one end protruding therefrom and adapted to receive a cog-wheel 39 thereon, which is separated therefrom by suitable insulation 40 and rigidly attached thereto by a suitable 3o set-screw 41. Theinner end of the said shaft 37 has a lug or boss 42 rigidly attached to the same. A lug 43 is attached to the upper side within the explosion-chamber 31 near the end of the shaft 37. The under face of the said 35 lug 43 is horizontal and provided with a fiat spring 44 on either side, which springs 44 extend beyond said lug 43 and engage with either end of a spring-holder 45, which ispivotally attached to the face of the lug 43.

4o Semicircnlar springs 4G of suitable length are rigidly attached one on either end of said holder 45, which springs 46 are adapted to be engaged by the lug or boss 42 on the end o the shaft 37.

A socket 47 is rigidly attached at a suitable point immediately below the chamber 31 on the cylinder-head 4. In said socket 47 one Y end of the journal of a spool 48, bearing a cog-wheel 49 on either end thereof, is inserted 5o and rigidly attached by means of a set-screw 50. One of said cog-wheels 49 is adapted to engage with the wheel 39, and the other engages with a cog-wheel 51, which is rigidly attached to the eccentric 22 concentrically with the shaft G. The wheel 51 is double the diameter of the wheels 49 and 39 for the purpose of giving the shaft 37 two revolutions to one of the main shaft 6. On either side of the valve 14 transversely in the cyliner 1 and 6o intersecting the passagesv 13 and ports 12 a rock-valve 52 is inserted, said valves 52 having on the front end a flange 53, which impinges upon the face of the cylinder 1, and the other sides of said valves have flanged nuts 54 attached thereon, which impinge upon the rear side of the cylinder. The valves 52 are formed by having aportion of the convex surface removed near the center on opposite sides, as shown in Fig. 2. On the front end of the valve 14 a collar 55 is rigidly secured for the double purpose of preventing the escape of steam or explosive mixture and for the operation of rocking levers 53, which are attached at one end eccentrically and pivotally on said collar 55, said levers 56 diverging therefrom and having their opposite ends pivotally attached eccentrically to the flanges 53 of the valves 52 for the purpose of rocking or oscillating said valves 52 simultaneously with the operation of the valve 14, which is manipulated by means of a lever 57, which is inserted on the front end and attached thereon by means of a nut 58.

The rear end of the valve 14 has an opening from the slot 15 communicating with the explosion-chamber 31. A pin or lug 59 protrudes from the upper edge of the valve 14 into the explosion-chamber 31 immediately above the spring-holder 45, which said lu g 59 is adapted to engage as the valve 14 is rocked to and fro. A lever-stop 60 is arranged on and attached to the cylinderl on either side` Suitable electrical connecof the lever 57. tion may be made with the core 33, as by the wire 61, and to any other convenient part of the engine. A suitable stuffing-box 62 is provided for the cylinder-head 4 at the entrance ofthe shaft G therein.

G3 represents a steam or explosive-mixture supply pipe communicating with the cut-off valve 17 and is adapted to conduct motive material to the cylinder. An exhaust-pipe 64 is arranged on eitherside to conduct the exhaust from the valves 52 as is desired. Pipes G5 are arranged on either side of the pipe G3 for the purpose of conducting water to and from the water-chamber 66, which is arranged with a partition transversely across the top, so as to compel the circulation of the water completely around the cylinder.

The mode of operating my improved combination steam and gas engine is as follows: All the parts having been properly adjusted, the lever 57 is thrown to the right against the lever-stop G0, which movement by means of the levers 56 rocks or tilts the valves 52 into the position shown in Fig. 2, wherein the steam or other motive mixture may be admitted through the pipe 63, cut-off 17 18, passages 1G and 13, angular passage 15 in the valve 14, the valve 52 at the left in Fig. 2, and the port 12 into the cylinder and against the abutments 10, where, if steam be used, its power is exerted in the usual manner, and when the abutments have been forced around the exhaust-steam escapes through the other port 12 to the right of Fig. 2 and is conducted as desired by the pipe 64. lf gas, naphtha, gasolene, or other explosive vapor is used, the same enters in the same manner as steam until the piston 7 and its abutments 10 reach a certain point in their revolution, whereupon the cut-off valve 17 18, being oscillated by tho eccentric 22, rod 25, and arm 21, shuts IOO IIO

off the passage 16, thereby shutting` said explosive vaporin the cylinder 1. The wheels 57 49 39, the shaft 37, and lug 42 having been properly adjusted, said lug 42 engages and disengages the spring 46, while the passage 16 is cut off by the valve 17 18, which by means of an electric current causes a spark and consequent explosion of the vapor within the cylllO inder, which causes the revolution of the piston 7 and shaft 6. The tilting of the lever 57 and rotation of the valve 14 cause the pin or lug 59 to engage with one end ofthe springholder 45, thereby depressing that end of said holder 45 and causing the spring 46 on that end to engage with the lug 42, as hereinbefore described. By arrangingthe lever 57 in neutralposition, as shown in Fig. y5, the lug 59 'assumes theposition shown .in Fig 4 and the springs 44 force the spring-holder 45 into` neutral position, .whereupon the lug 42 may revolve without an electrical contact. W'hen the lever 57 is reversed, the pin or lug 59 en-A gages the reverse end of the spring-holder 45, causing the reverse-spring 46 to come in contact with the .lug 42. -The valve 14 communicates with Athe passage 13 on the other side, and the Valves 52'by means of the levers 56 are reversed in position, changing from an ex-l haust; to a live port, and Vice versa. In this position the motive material enters the oppo-v site side of the cylinder and. themotion of all` parts is reversed.

Iam well aware thatrotary engines have been made which run by'stealn-power which comprise a piston arranged eccentrically within the cylinder and are operated by abut- 13; the said passages l2, 64, and'13, intersect-f: ing at common points, thevpassage'l6, the supply-passage 63, for gas, thecut-off `valve 17 i d'1 i *interposed between thev passages 63 and-16,`

v V6o the strap surrounding said eccentricandxadf justably connected to the crank on the stem of the valve 17, thelever 57 connected with'` the rocking valves 52, and suitable means for igniting explosive mixture in the chamber 31,

all substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.'
